The Mrs. Miniver story was later adapted into a film of the same name and starred Greer Garson in the titular role for which she won the Academy Award for Best Actress.
On the outbreak of war, this book became the basis for a patriotic and sentimental American film, Mrs. Miniver, released in 1942, which won six Academy Awards, including Best Picture.
Struther stopped the regular newspaper columns that year, but wrote a series of letters from Mrs. Miniver, expanding on the character's wartime experiences.
Under the influence of the American Office of War Information, the film attempted to undermine Hollywood's prewar depiction of Britain as a glamorous bastion of social privilege, anachronistic habits and snobbery in favour of more democratic, modern images.
To this end, the social status enjoyed by the Miniver family in the print version was downgraded and increased attention was given to the erosion of class barriers under the pressures of wartime.
In 1944, CBS Radio presented a Friday-night series named Mrs. Miniver starring Judith Evelyn and Karl Swenson.
